Headblock for pressers



UNITED STATES PATENT OFFICE.

EDWARD CARL RUDOLL, OF RICE LAKE, WISCONSIN.

HEALDBLOCK FOR PRESSERS.

T 0 all whom it may concern:

Be it known that I, EDWARD C. RnnoLL, a citizen of the United States, and a resident of Rice Lake, in the county of Barron and State of lVisconsin, have invented a new and Improved Headblock for Pressers, of which the following is a full, clear, and exact description.

This invention relates to improvements in headblocks for pressers, and more particularly to head blocks adapted for use in connection with excelsior, hay, or other similar form of pressers in which the head blocks are at intervals between bales, an object of the invention being to provide an improved construction of head block providing grooves for the accommodation of single or double'bale tying wires and which is so constructed as to efficiently house the wire and yet permit the removal of the wire as occaslon may requ1re.

A further object is to provide a head block of the character stated which .can be manufactured and sold at a reasonably low price and which will be strong and durable in use.

With these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claim.

In the accompanying drawings- Figure 1 is a diagrammatic elevation illustrating the normal use of one of my improved head blocks.

Fig. 2 is a view in elevation of one of the head blocks removed.

Fig. 3 is an edge View of the head blocks shown in Fig. 2.

1 represents an ordinary baling press and 2 my improved head which is located in the press and provides accommodation for wires 3 to operate as bale ties, and while I have illustrated in Fig. l a head block pro vided with three of these wires, it is obvious that two wires or even a single wire may be employed as an eflective bale tie.

The invention resides in the particular construction of head block as I may employ the same in connection with any type of baling press.

The head block 2 comprises a central Specification of Letters Patent.

board or plate 4 having secured to opposite sides parallel boards 5, 6, 7 and 8, said boards spaced apart providing wire receiving grooves 9 in opposite sides of the head block.

It will be noted that these grooves 9 have two straight walls at right angles to each other and one beveled wall 10 so that the grooves are narrowest at their outer portions and increase in width or thickness to their inner ends. I may provide these beveled walls 10 on any of the boards 5, 6, 7 and 8, but preferably provide only one beveled wall in each groove as clearly shown in Fig. 3.

Metal straps 11 are secured around the edges of the head block and form reinforcing plates 12 at the ends of the upper and lower grooves, hence, the metal straps not only strengthen the head blocks, but also act as wear plates to lengthen the life of the head block when in use. The ends of the grooves are flared, as shown at 13, and provide ready entrances and exits for the wires.

By providing the grooves 9 with two straight walls at right angles to each other and a beveled or inclined wall, I am enabled to remove the wires readily in the baling operation, but at the same time during the formation of the bale by the press, the wires will be securely held in their grooves and as above stated, I employ three sets of grooves on each side of the head block so that I may employ a single baling wire in the central groove, or a pair of baling wires in the outer grooves, or three baling wires accommodated in all of the grooves as illustrated in Fig. 1.

Various slight changes might be made in the general form and arrangement of parts described without departing from the invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claim.

I claim:

' A head block of the character described, comprising a supporting board or plate, parallel boards secured to said supporting board and spaced apart, metal strips secured around the ends of the head block and embedded in the surfaces of the ends and the side faces 01"- the head block providing wear plates at the edges of the grooves, said boards providing by reason of their spacing three grooves on each side of the head block, each of said grooves having a pair of walls at right angles to-eaohother, and a third inclined wall, whereby said grooves are narrowest at their entrances and of greatest width at their inner portions, the grooves midway the ends of the boards being adapt- 10 ed for use in connection with a single wire bale tie and the end grooves for double wire bale tie. l
